I think it’d be super cool if you could unlock and add all the class skill lines on one character — but only after you max out all the passive skills for your main class first. Once you’ve done that, you’d be able to dive into other class skill lines and really mix things up. It’d let players build crazy unique setups and bring way more variety to how you play. Kinda like the Path of Exile skill tree, where you can just go wild and make your character totally your own.
